Your Optimus PRO-SW100P 100-Watt
Powered Subwoofer is designed to
give you the best possible low frequency sound quality for the ultimate
home theater experience. You will be
astonished by the realism it adds to
movie sound effects and the power it
lends to all kinds of music.
The subwoofer com bin es the power of
a built-in 100-watt RMS amplifier with
a responsive, 10-inch coated paper
cone woofer — all housed in a ported
bass-reflex enclosure to prod uce tight,
floor-rumbling, powerful bass (down to
42 Hz) that you can feel as well as
hear! The LED power indicator lets
you see at a glance when the subwoofer is operating.

SAFETY INSTRUCTIONS
• Never open the cabi net or remove
the metal control panel, as this
might result in electrical shock or
damage to the unit.
If your PRO-SW100P needs servicing, contact your local RadioShack store.
• To prevent electrical shock, do not
use this polarized plug with an
extension cord receptacle or other
outlet unless the blades can be
fully inserted to prevent blade
exposure.
• Unplug the PRO -SW 100P’s power
cord from the electrical outlet if it
will be left unused for a long time.
• Only connect this uni t to a power
supply of the type desc ribed in t he
operating instructions or marked
on the unit.
• Route the power-supply cord so it
is not likely to be walked on or
pinched by items placed upon or
against it, especially a t plugs, convenience receptacles, and the
point where it exits from the unit.
• Placing the subwoofer on the
same stand or shelf as your turntable can result in low frequency
rumble or acoustic feedback.
Cautions :
• To prevent fire or shock, do not
expose this subwoofer to rain or
moisture.
• Do not place the subwoofer with
its metal plate against the floor.

40-408 0.fm Page 3 Wednesday, August 11, 1999 10:58 AM
• Place the subwoofer away from
heat sources such as radiators,
stoves, or other appliances that
produce heat.
CHOOSING A LOCATION
Cautions:
• To prevent the ca binet from warping or discoloring, do not place the
subwoofer in a place where it is
exposed to direct sunlight or
excessive humidit y.
• Do not place the subwoofer where
it might be knocked over or
exposed to falling objects.
• The metal control panel on the
back of the P RO-SW1 00P acts as
the heat sink for the subwoofer’s
internal amplifier. Therefore, place
the unit at least 4 inches (10 cm)
away from a wall, and do not let
anything come into contact with
this panel.
Where and how you position your subwoofer greatly affects its bass response. Adjusting the subwoofer’s
volume control in relation to the left
and right speakers and adjusting the
subwoofer’s high cut filter also affects
your speakers’ overall sound.
Although low frequencies are non- directional, factors such as room reflections, standing waves, resonance and
absorption strongly affect your subwoofer’s performance. For maximum
bass output, place your subwoofer in a
corner. To reduce output, move it
away from corners and back walls.
Even slightly moving the subwoofer
can have a major effect on bass response.
We recommend that you test the subwoofer in different locations to determine where the best balance is
between your satellite speakers (if
used) and subwoofer. We also recommend that you place the PROSW100P at least 4 inches a way from
the wall, and at least 2–3 feet away
from your television or computer’s disk
drive system so the s ubwoofer’s magnet will not distort the colors of your TV
picture or erase your floppy disks.
CONNECTING TO AN
AMPLIFIER
You can connect your PRO-SW100P
to an amplifier/receiver’s line out or
speaker terminals.
Notes:
• We recommend you connect the
subwoofer to an amplifier or
receiver that has at least two sets
of line out j a cks. If your ampli fi e r o r
receiver has only one set of line
out jacks, you might not hear any
sound f rom the s atellite spe akers.
If your amplifier or receiver has
only one set of line out jacks, follow the instructions under “Connecting to Speaker Terminals”
instead.
• Your PRO-SW100P can also be
connected to your television if your
television has line out jacks.
